Sony PDD media (Score 1)

Archiving digital video and audio can be a daunting challenge. Many groups in the television broadcast industry have grappled with this issue for years. Some have settled on expensive spinning disk-based storage such as NAS and SAN solutions. Others have found value in tape-based robotics libraries for massive archival arrays. Recent advances in optical storage technologies have led to the development of Sony's Professional Disk for Data. The optical disks used in this technology have the same physical dimensions of a typical CD or DVD disk, but can store 23.3GB (about 2 hours at DV-25) for 50 years or more. Sony markets these disks in a cartridge-based format (primarily because these new disks don't yet have a protective coating like CD's and DVD's, making them more susceptible to damage from particulate matter). Bare media is available for use in specialty applications such as Asaca's AM750PD robotics library. For the typical user, I would recommend cartridge-based media for practical day-to-day use.
